- Title:
- Effect and Benefit Evaluation of Coating for Controlling Limnoperna fortunei on Culvert Roughness
- 摘要:
- 淡水壳菜附着于输水管涵内壁，会侵蚀混凝土结构,增大管壁糙率，从而增加输水能耗和工程运行成本。选用物理法中的特种防护涂料保护法在某工程现场开展试验，将SBS、ZH2000B、GX-BIOX和G-Ⅱ等不同涂料对淡水壳菜的防护效果进行对比分析。试验结果表明，GX-BIOX涂料防生物附着效果最佳，G-Ⅱ、SBS和ZH2000B涂料防护性相对较差。选择GX-BIOX涂料在该工程反虹涵进行应用，通水运行一年后，管涵无淡水壳菜附着，防护效果良好，且内壁表面光滑，平均糙率从0.017 2降至0.009 6，大幅降低了输水能耗，具有良好的经济效益、社会环境效益和生态效益。
- Abstract:
- Limnoperna fortunei attached to the inner wall of culvert may cause concrete erosion and roughness increase, thus increasing the energy consumption and project operation cost. Herein, special protective coating was selected from physical measures to carry out tests in a project site, and the protective effects of different coatings such as SBS, ZH2000B, GX-BIOX and G-Ⅱ on Limnoperna fortunei were compared. The results show that GX-BIOX coating has the best anti-biological adhesion effect, while G-Ⅱ, SBS and ZH2000B coatings have poor protection. Application of GX-BIOX coating in the inverted siphon culvert realized no Limnoperna fortunei attachment and good protection effect after operating for one year. The culvert inner wall was smooth and the average roughness decreased from 0.017 2 to 0.009 6, which remarkably reduced water conveyance energy consumption and has good economic, social environmental and ecological benefits.
